Abstract

495,879. Adjusting wireless apparatus; indicating-apparatus. BIRDSEYE, L. F. May 26, 1937, No. 14566. [Class 37] [Also in Group XIX] An indicator particularly for a radio-receiver, comprises a pointer 9, for example a metal strip, bent to provide a plurality of facets, and rotatably mounted about its longitudinal axis so that in each of the positions shown, for example, at a, b, c, d, a different edge of one of the various facets co-operates with a respective scale 4, 5, 6, 7, on a dial 8 which may be illuminated by rear or edge lighting in known manner. The operative facet edge may be distinctively coloured similarly to its respective scale and indicia marked on the visible facets; as shown, to indicate the operative edge. The pointer is rotatably mounted on a carriage 10 moved, in known manner, along a guide 11 by a cord 12 during tuning of the receiver. The cord is anchored at one end to the carriage and at the other end is wound round a pulley 15 rigid with the pointer. The cord also passes round a pulley 14 on an arm 16 rocked when the wave range change switch 17 is operated to vary the effective length of the cord and thereby rotate the pointer to the appropriate position against the action of a spring acting on the pointer. The number of scales may vary and they may be arcuate in which case the pointer describes an are when traversing them.
